Is this the best Jasper Circle Guide for cutting holes in MDF and Baltic Birch for flush mounting 12" and 15" woofers?

I think so. it allows for very small incremental changes in diameter. I used to use my own personal adaptation of a circle jig but this is very accurate, sturdy and easy to use. My only complaint is that it can be easy to loose the 'pivot' pin (center of the circle).

A drill press is really the way to go if you can lay the material flat. Otherwise, any corded drill is really better for large hole saws than a cordless

8" hole is perfect. It comes with its owe template. Easiest speakers I ever installed.

Honestly if your that worried about the quality in your enclosure you should simply build it yourself. This box is air tight but the mdf used is 1/2 in. which has been known to flex which will cause a decrease in bass production also, this enclosure will likely not meet the manufacturers specifications for volume futher more decreasing bass production.

I use the Bosch RA1181 bench top table (review here http://www.amazon.com/Bosch-RA1181-Benchtop-Router-Table/dp/B000H12DQ6/ref=cm_cr-mr-title). It takes some work to make it right, but for the price I like it. The router plate is already drilled for mounting and has a hole for above table depth adj, which I find very helpful. The adj works well, but you will have to reach under the table to change the range of bit height adjustment. Above the table height works once you get the base "in the range". I use offset wrenches (review here http://www.amazon.com/Offset-Wrench-Triton-Peachtree-Woodworking/dp/B0040BLFZE/ref=cm_cr-mr-title) for bit changes - this is for the nut, I have another for the shaft - that work far better than the straight wrenches that came with my 1617EVS router, well worth the $.

If you have the SM152's then you have 15" woofers in those. The SM 122's have 12". I have owned both. I now have Polk audio rti8's and Monitor 70'S. Though I don't have a pair of the RTIA9's I can say the RTI8's and Monitor 70's have good bass for the size they are. The infinity SM 152'S I owned had really good deep tight bass. As I recall the Infinitys were more efficient than these Polks. Something like 105 DB 1W1M. These Polks will need a decent amp to drive them properly to get their full potential.

I use a Bosch HS1926 5-3/8-Inch x 16-Inch Round Spade - SDS MAX Shank and am very happy with the results.

The template SOSS makes is the thing to use. A bit of cash, but tuned for the job. I'm using 208s and they sit close to the edge.

If your cutting a 16D (Typical Framing nail), plan on 1/16". I honestly feel that Knipex is the finsest bolt cutter for flush cutting........Knipex is by far the best quality hand tool available. Certainly a wise investment.

Dayton Audio's web site has this information and more details: http://www.daytonaudio.com/index.php/dc160-8-6-1-2-classic-woofer.html There the baffle cut-out is specified as 144.6 mm, which is a little less than 5&3/4". There is a drawing and many more design details at: http://www.daytonaudio.com/media/resources/295-305-dayton-audio-dc160-8-specifications-46146.pdf

The Axial Glide Mechanism of the Bosch GCM12SD allows you to mount the saw up against a wall, and still retain 14" horizontal cut capacity. The rear extension bars of the Bosch 5312 extend behind the saw when cutting, making a wall mount cut station impossible without cutting holes in the wall allowing the bars to slide into. The Axial Glide Mechanism on the CGM12SD is worth the extra money, much more versatile tool, great for job site work and of course for a single point cut station in a shop. I love mine, use it every day.

There is a template that comes with the speakers to cut the hole. I think the speaker is 8 to 10 inches round and the hold is actually just a bit smaller. I didn't install since these needed to be wired into our home automation system. Sound is decent, we have them on a covered porch above our hot tub.

you should not need a spacer the speaker is sufficiently padded around the edge and the woofer excursion is not that long.

This jig will work on stock 2 1/4" thick. I love the jig and happened to have used it just today. I sometimes use it with some 3/8" pointed inserts (sorry I don't remember their names) for mating the dowel holes to uneven stock. The unique feature of this jig to center the drilling guide to the stock is unsurpassed. I know it is expensive, but it is very well built and I know of no other centering jig of its equal. I would definitely buy it again.
